1. 1. Pancreatic Endocrine Tumourigenesis : Genes of potential importance

   Författare :Térèse A. Johansson; Barbro Eriksson; Britt Skogseid; Gunnar Westin; Martin Bäckdahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic endocrine tumour; Multiple endocrine neoplasia type 1; Tumourigenesis; Notch signalling; Notch1; Hes1; Neurog3; Neurod1; Men1; Ascl1; Pou3f4; Pdx1; Rpl10; Dlk1; Dkk1; Tph1; menin; Tumour biology; Tumörbiologi;

   Sammanfattning : Understanding signalling pathways that control pancreatic endocrine tumour (PET) development and proliferation may reveal novel targets for therapeutic intervention. The pathogenesis for sporadic and hereditary PETs, apart from mutations of the MEN1 and VHL tumour suppressor genes, is still elusive. LÄS MER

3. 2. Tumour Biological Factors Characterizing Metastasizing Serotonin-producing Ileocaecal Carcinoids

   Författare :Janet Lynn Cunningham; Eva Tiensuu Janson; Kjell Öberg; Irvin M. Modlin; Uppsala universitet; []
   Nyckelord :Internal medicine; endocrine tumour; midgut carcinoid; serotonin-producing neuroendocrine carcinoma; prognosis; morphology; tachykinin; connective tissue growth factor; islet autoantigen-2; morphology; carcinoid syndrome; Invärtesmedicin;

   Sammanfattning : In this study, metastasizing serotonin-producing ileocaecal carcinoid tumours (MSPCs) were examined for biological characteristics that could be used to define clinically relevant subgroups within this patient population. Possible targets for new treatment options were also explored. LÄS MER

4. 3. Life Style, Molecular Pathology, and Breast Cancer Risk

   Författare :Signe Borgquist; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hormone receptors; Breast cancer; tissue microarray; histopathology; ERβ; tumour proliferation; cyclin D1; p27; HMG-CoA reductas; life style factors; diet; hormone replacement therapy; obesity; endocrine therapy;

   Sammanfattning : The breast cancer diagnosis covers a wide range of tumours with different geno- and phenotypic characteristics. The diversity among studies on life-style factors and their impact on breast cancer risk might be clarified by recognizing breast cancer as a heterogeneous disease. LÄS MER

5. 4. Endocrine tumour development : with special focus on chromosome arms 1p and 11q

   Författare :Brita Nord; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Endocrine tumour; Follicular thyroid tumour; Malignant melanoma; Midgut carcinoid; Pheochromocytoma; Abdominal paraganglioma; Merkel cell carcinoma; MEN1; SDHD; RIZ;

   Sammanfattning : The overall goal of this thesis has been to characterise the involvement of chromosome arms 1p and 11 q in the development of endocrine tumours. The MEN1 gene was analysed as a candidate tumour suppressor gene by screening for mutations in follicular thyroid tumours, malignant melanomas, pheochromocytomas, and abdominal paragangliomas.

7. 5. Characterization of Endocrine Cells and Tumours in the Stomach

   Författare :Apostolos V. Tsolakis; Eva T. Janson; Mats Stridsberg; Guida M. Portela-Gomes; Ola Nilsson; Uppsala universitet; []
   Nyckelord :Oncology; ECL cells; ghrelin cells; gastric endocrine tumours; VMAT-2; ghrelin; obestatin; HDC; U-MeImAA; Onkologi;

   Sammanfattning : Enterochromaffin-like (ECL) and ghrelin cells, in the human gastric mucosa and in gastric endocrine tumours (GETs), were subclassified with respect to immunohistochemical reaction vs. vesicular monoamine transporter 2 (VMAT-2), ghrelin/obestatin, and histidine decarboxylase (HDC).
